Application May 23, 1935, Serial No. 23,081l

I 2 Claims.

This invention relates to a door hinge, the general object of theinvention lacing to so construct and arrange the hinge that it is hiddenfrom view, with means whereby the hinge can be adjusted to align thedoor.

This invention also consists in certain other features of constructionand in the combination and arrangement of several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcon'espondingparts throughout the several views, and in whichz- Figure 1 is a.transverse sectional view through a portion of a door and a door frameshowing the invention in use with a door and frame constructed of metal.

Figure 2 is a similar view but showing the door in open position.

Figure 3 is a view of the section of the hinge which is connected to theframe of the door.

As shown in the drawing the numeral I indi-- cates a flat leaf of ahinge which is to be connected to a post 2 on the frame and the numeral3 indicates a substantially U-shaped leaf which has its outer limbadapted to be connected to the recess part Lof the post or pillar 5 ofthe door A. 'I'he other limb of the U-shaped part curves outwardly andis formed with a knuckle part 6 through which the hinge pin 1 passes,the pin also passes through the knuckles 8 of the leaf I, the knuckle 6fitting between the knuckles 8. A projection 9 is formed on the knuckle6 for engaging a part of the leaf I to limit opening movement of thedoor as shown in Figure 2. A screw I0 passes through a countersunk holein the knuckle car'- rying limb of the leaf 3 with its head countersunkin said hole and said screw passes into a l threaded opening in theother limb and lock nuts II are threaded on the screw and engage the ad-45 jacent faces of the two limbs as shown. This screw strengthens theU-shaped leaf 3 and pro- Figure 4 is a view of the opposite hinge.' f

vides means whereby the hinge can be adjusted to align a. door.

When the hinge is positioned as shown in Figures 1 and 2 it will occupythe recess B formed between the posts 2 and 5 when the door is closed 5so that the hinge will be hidden from view as shown in Figure 1. Thepost 2 is formed with the recessed part 2' for receiving the knuckles ofthe .hinge and reinforcing plates I 2 are placed on the inner faces ofthe outer parts of the post l0 to receive the screws fastening theleaves to the parts as shown in Figures 1 and 2. However, if the hingeis to` be used on a wooden construction the outer limb can be extendedat the side as shown at I3 in Figure 4 in dotted lines and the 15 screwspass through these extensions. 'Ihis will enable large screws to be usedfor fastening the A U-shaped leaf to the door, it being understood thatwhen the outer limb of the U-shaped leaf is of the same width as theother limb and small 20 screws must be used and such screws are to beplaced in threaded holes through the space between the limbs.

It is thought from the foregoing description that the advantages andnovel features of the in- 25 vention will be readily apparent.

-It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts. provided thansuch changes fau within the scope of the so' appended claims.

What is claimed is:-

1. A concealed hinge comprising a iiat leaf,

a U-shaped leaf having an end of one limb hingedly connected to thefirst leaf, and means passing through the two limbs ofthe U-shaped leaffor reinforcing said leaf and for adjusting the distance between the twolimbs.

2. A concealed hinge comprising a nat leaf, a U-shaped leaf having anend of one limb hinged- 40 ly conected to the first leaf, the other limbbeing adapted to be connected to a door, and a screw passing through thetwo limbs for reinforcing the limbs and for aligning the door.
